[@galinrashkov7645]

I would recommend using bearings on each wheel and decrease significantly the gaps between the different gears (Use teflon rings)

[@zeicanofficial]

Exactly what I was thinking, I was really thinking it would significantly decrease friction.

[@ghostlyninja125]

Journal bearings would be best

[@Xavier1...]

I'm guessing that adding a lubricant like oil would also decrease friction? Maybe transmission fluid idk?

[@wachocs16]

Also add a chanfer on the bed side of the print. You can se the first gold gear to have a big elephant foot (Layers squished at the bottom) and maybe add grease Teflon or brass washers would be good to pack them more thingly and reduce vibration Also this type of gears are really dangerous at high speed. Never be over the axis of rotation. If you reach really high speed inside your house you can get your ceiling damaged, electrodomestics and pets

[@oeliku3033]

Some suggestions: 1. use spacers on the axle, so the gears are fixed on there to prevent wobbling and gears grinding against each other 2. use a normal M8 steel bolt instead of the aluminum rod and screw it far enough in, so you dont get vibrations in the gears. That way, the gears wont come loose as well 3. use ball bearings on the housing AND the gears 4. reduce the contact area of the higher gears. So 1st gear has the most contact area and so on 5. lube the gears and bearings 6. print the grip sideways. so it doeant brake (obvsly) 7 maybe try different gear geometries. there a some that are better for high torque or high speed. the latter have much less drag. 8. you can safe an enourmous amount of weight on the last gears. make them much thinner then they are now

[@spaceenjoyer42]

Nice suggestions 👍

[@gumby5068]

Can’t put ball bearings on the gears that’s not how gears work. (At least the input gear thinking about it now ig all the other ones could)

[@andrewkarsten5268]

@@gumby5068 he’s saying put the ball bearings where the gears are connecting to the axel. That way, the gears have less friction trying to spin. Like how skateboard wheels are connected to the trucks, they have ball bearings to decrease friction

[@zippythinginvention]

I've had a curiosity for a long time: how to extract energy from something that's very heavy, but moving very slowly. I present the challenge to you: how much energy can you extract from a falling weight? Or, how long can you keep a system moving, while only dropping a weight a short distance? Ultimately, the scenario that fascinates me most is glaciers. It would seem there's a very large amount of potential energy there.

[@SjaakWWortel]

Wait until the glaciers melt and build a hydroelectric generator/dam

[@zippythinginvention]

@@SjaakWWortel haha

[@monad_tcp]

While you are there, wait for the tundra to melt, now you increased the arable land 4000% near the artic.

[@monad_tcp]

You also get more wind power as a side effect, perhaps even too much of it, as more energy is freed into the system, a couple of tornadoes here and there, not big of a deal. And your coastal lines might change by a couple of meters. That's a minor deal thou, who would build anything on beaches anyway. Lots of erosion already.

you can add a worm gear for rotating the slowest or the main driver gear as it needs more force to rotate other gears

@@JoachimVampire he can add small metal worm gear , actually my perspective is , as worm gears have to much load capacity ans speeed reduction we have to give less force with hand so there will be less chance of breaking of gears
